Need help with: Vola - Gutter Moon.

hello i've just recently found this band and that song and i am simply obsessing over it D:

I've tried to figure out how to play the song, but i am not the best when it comes to learning a song by ear.and i am really lacking in the Chord side of guitar playing. So i've come here in hopes of someone helping me out with learning this song

I have a few information and a part of a riff figured out. Not 100% sure if it is played right or if the Tuning is right. But as fare as the information i have gathered i have seen People say it is Played on a 7 String guitar with F# standard tuning (high to low :BF#DAEBF#)

Edit: I have figured the end part of the riff out no only need the end part of riff nr 2.

And as for the riff it starts at 2:09 has a few tremolo picking and then by the end it has this run down witch i have,'t figured out yet in the video below you can see by the end of the video a rotoscope style animation but it is of a Bass i belive so i do not know if that part is only played by a bass or not.
